Specification of Letters Patent.
Patented Dec. 12, 1916.
Application filed January 31, 1916. Serial No. 75,317.
To all whom t may concern.'
Be it known that I, HENRY J. FRITZ, a citi- Zen of the United States, and resident of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and usei'ul Window-Lock Device, of which the following is a speciiication.
The object of my invention is to provide a window lock device of simple, durable and inexpensive construction, which may be secured at any desired point on one sash or a two-sash window.
A further object is to provide such a device which will serve to limit the relative opening movement of the sashes while permitting other sashes to be moved a limited distance, and which can by simple and easy manipulation be moved to position for allowing full movement of the other sash members.
My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:
Figure 1 shows a front or inside' elevation of a window equipped with a window lock device embodying my invention. Fig. 2 shows an enlarged detail front view of my device installed on a window sash. Fig. 3 shows a top or plan view of the same in position for limiting the movement of the sash. Fig. 4 shows a similar view with the device in its open position for permitting free movement of the sash members. Fig. 5 shows an inverted, plan view of the device installed on the sash member. Fig. 6 shows a front view of a modied form of the device. Fig. 7 shows a vertical sectional view of the same, part of the device shown in Fig. 6. Fig. 8 shows a front elevation partly broken away of still another form oimy device, and Fig. 9 shows a vertical, sectional view of the upper portion of the form of the device shown in Fig. 8.
In the accompanying drawings, I have shown several forms of my device. In the form of the device shown in Figs. 1 to 5 inclusive, I have used the reference numeral 10 to indicate generally a frame in which is slidably mounted an upper window sash 11, and the lower window sash 12. My improved device in each case consists of two plates or members hinged together in a manner to accomplish my purpose. In the form of my device shown in Figs. 1 to 5, one of said plates indicated by the reference character 13 is designed to be secured to the stile of the upper window sash 11 at a point spaced above the lower window sash 12, by means of screws or the like 14.
In the form of the device now being described, the plate 13 has a central lateral eX- tension' 15 forming a bearing or knuckle. The other plate 16 has lateral extensions 17 and 13 forming upper and lower bearings or knuckles spaced from each other above and below respectively, and alined with the bearing or knuckle 15. Received in thebearings 15, 17 and 18 is a pintle 19 which extends upwardly beyond the upper knuckle of the plates, as clearly shown in the drawings. At the lower end of the plate 13 is an outwardly extending flange 20. At the lower end of the plate 16 is an outwardly extending horizontal flange 21, lying in a plane just above the horizontal plane of the plate 20, so that when the plate 16 is rotated to the position shown in Figs. 2, and 3 the flange 21 rests just above and overlaps the iiange 20. In the walls of the bearings 15 and 17, in the adjacent edges thereof, are slots 22 and 23, which are alined when the plate 16 is in the position last described.
The pintle 19 is provided with some means such, for instance, as the pin 24 adapted to extend into the slots 22 and 23, when the parts are in the position shown in Fig. 2, for preventing relative rotation of the bearings of the plates 13 and 16, thereby holding the device in the position shown in said Fig. 2. `Nhen the device is in such position, the flange 21 stands in the path oi" the upward movement or' the lower sash 12, thereby limiting the relative sliding movement of the window sash. It will be seen that the upper sash may be lowered, or the lower sash raised, or each sash raised a certain distance, but that the total movement is limited by the ange 21. It may be mentioned, incidentally, that the flange 21 is so arranged as to cover the lower end of the bearing 18, as clearly shownin Fig. 5, so that a wire or other instrument inserted between the lower part of the upper sash, and the upper' part of the lower sash could not be manipulated for releasing my device. It will be noted from the showing in Figs. 3, 4 and 5, that the edge of the flange 21, which rests adjacent to the plate 13 when the parts are locked, is straight, while the other edge of the flange 21 is curved. llVhen, however,
it is desired to release the device and permit the free sliding movement of the saslies, the upper end of the pintle 19 is grasped and raiseduntil a suitable engaging means, suchV as the pins 24, is received in the slot 23. When the pintle 19 may be rotated for moving the plate 1G from its position .shown in Fig. 3 to its position shown in Fig. 4, where it stands out oiE the path of travel of the lower sash. The window sash may then be raised or lowered for cleaning them or for ventilation or for any other desired pur- Jose. 1 In Fig. 6, I have shown a .slightly modified forni of the device, comprising a plate 30 corresponding to the plate 13, and adapted to be secured to the stile of' the upper sash and having pairs of spaced alined bearings or knuckles 31 formed at one side edge, and designed to project beyond the stile of the window sash. rlhe other pla-te 33 has an alined pair of bearings or knuckles 33 designed to be alined with the bearings 31. Mounted in the bearings is a pintle 34 which projects beyond the upper bearing. The pintle 34, just above the upper bearing 31, has a laterally extending lug 35, designed in one position of the movement of the plate 32 to stand above thenoteh 36 in the `wall of the bearing 31 and to be dropped into said notch when the pintle 34 is slightly lowered. 1n the lower end of the pintle 34 is a pin 37 extending in a vertically elongated slot 38, in the lower bearing 33. The pin 37 and slot 38 limit the upward movement of the pintle 34 and permit such longitudinal movement thereorl as is necessary for the operation oiE the lug 35. The plate 30 has the laterally extending flange 39 at its lower end, and the plate 32 has the laterally extending flange 40 at its lower end, just above the level of the flange 39. The flanges 39 and 40 are .similar in shape and relative arrangement to the flanges 2() and 21.
Vlt will'be seen that when the plate 32 is v in position, where the flange 40 rests Vabove .the flange 39 and engages the plate 30, the
Y rlhe device shown'inFig. Gmay be'formed with the lower part of the bearing 33Y of somewhat larger diameter than the pintle 34,leaving a space'to receive a coil spring 41 which abuts against the shoulder 42 of the bearing 33, at its upper end, and against a pin 43 at its lower end. rlhe pin 43 is extended through the pintle 34 and projects into the slot 38.
ln Fig. 3 l have shown another forni of my invention, comprising the plate 30,
vsimilar to that already described having a flange 39 and the laterally extending aliued bearings or knuckles 44 and 45. rlhe plate 4G has the bearings or knuckles 47 and 4S alined with each other and with the bearings 45 and 44. Received in the bearings 44, 40, 47 and 48 is a pintle 49 having at its lower end a pin 50 which extends into an opening 51 in the bearing 47. Mounted on the upper end of the pintle 49, which projects above the bearing 45, is a sleeve 52 of greater diameter than the pintle 49 having` a plug 53 screwed into its upper end. Screwed on to the upper end of the pintle 49 is a collar 54. Extended through the pintle 49, spaced above the collar 54, is a pin 55 which extends into an elongated slot 56 on opposite sides of the sleeve 52. Mounted within the sleeve 52 surrounding the pintle 49, between the collar 54 and pin 55, is a coil spring 57. Formed on the sleeve 52 on the lower edge thereof, is a lug 58, which, when the plate 46 is in position where the flange 51 engages the plate 30, is adapted to drop into the notch 59 in the upper end of the wall of the bearing 45. The pin 55 is extended through a vertically elongated slot 56 in the pintle 49, so that the ends of the pin 55 may engage the walls of the sleeve 52 and yieldingly press said sleeve downwardly.
When it is desired to release the device shown in Figs. 8 and 9, the sleeve 52 is grasped and raised upwardly for removing the lug 5S from the notch 59, and is rotated, thereby moving the flange 51 out of the path of the lower window sash.
It will be noted that the upper ends of the pintles 19 and 34, and thc plug 53 are tapered, so that it would be impossible to slip ordinary tools between the window sash and raise the bolt of' my device for releas` ing it.
Y* The advantages of my device are largely seen from the foregoing description. My device is of comparatively simple construction, and could be made at a small price from inexpensive material and can be installed on the window very easily. It can be installed at various points on the window for regulating the distance which the wirr dow can be lowered or raised, and by very without departing from the essential features and purposes thereof, and it is my intention to cover by this application any such changes which may be included within the scope of the following claim.
I claim as my invention:
In a window lock, a pair of plates having adjacent edges provided with alined knuckles, arranged to alternate with each other, a pintle received in said knuckles, and projecting above the upper knuckle, said pintle and knuckles having coacting means for locking the plates against hinged inovement with relation to each other when in one of their positions, one of said plates being designed to be secured to the upright member of the frame of a window sash, and having at its lower edge an outwardly eX- tending flange, the other of said plates having at its lower edge a laterally extending flange, a portion of which stands below the lower end of the pintle, and a portion of which is designed to overlap the first flange to prevent access vto the edge of the second flange from below for swinging the last mentioned hinged plate.
